How to loop through all Amazon API array Book results in PHP - php

Question

I am trying to consume an Amazon Product API and I choose to search for books alone base on the user search query. However after converting the response to an array, I am having problem looping through all the result without having to specify an index.
Below is my Code:
<div class="album py-5 bg-light">
<div class="container">
<div class="row">
<?php
foreach($formattedResponse as $response) {
?>
<div class="col-md-8">
<div class="card mb-4 box-shadow">
<img class="card-img-top" data-src="" alt="Card image cap">
<div class="card-body">
<p class="card-text"></p>
<div class="d-flex justify-content-between align-items-center">
<div class="btn-group">
<button type="button" class="btn btn-sm btn-outline-secondary">Arthur: <?php echo $response['Item'][0]['ItemAttributes']['Author']; ?></button>
<button type="button" class="btn btn-sm btn-outline-secondary">Title: <?php echo $response['Item'][0]['ItemAttributes']['Title']; ?></button>
</div>
<small class="text-muted">Price: <?php echo $response['Item'][0]['ItemAttributes']['ListPrice']['FormattedPrice']; ?> </small>
</div>
</div>
</div>
</div>
<?php
}
?>
</div>
</div>
</div>
Displaying the results works perfectly, the only drawback is, it fetches only the first index of the returned book response out of the thousands present because I used $response['Item'][0] if I take away the [0] from I get an error.. Below is the result
Arthur: Harry Boone Porter
Title: The Day of Light
Price: $8.00
My Question:
The array contains [0],[1],[2] to [1000] How can I fetch all the book results in the above format instead of the first index which I am using.

Seems like formatted response is the named array and does not have to be iterated with foreach loop, if I'm not mistaken, you just need to:
Pass to the view not the $formattedResponse but $formattedResponse['item'] and not to iterate through it. Lets call it $items.
$items = $formattedResponse['item'];
// pass $items to the view.
In ['item'] element you have an indexed array with numbers. So iterate through it
<?php foreach ($items as $item): ?>
... html here
<?= htmlspecialchars($item['ItemAttributes']['ListPrice']['FormattedPrice']) ?>
<?php endforeach; ?>
Do not forget to escape output for your views. Use Twig, Blade or something like Html::encode($var) from Yii. How to escape output in PHP
To make debugging of multidimensional large arrays easier install larapack/dd from composer, and add
dd($largeArray)
in any place of your code. It's like var_dump, but a lot easier to look for human being ;)
